To all whom it may concern."

Be it known that l, Josnrii Satire, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Electriorlpplizines-Receiving and Meter-Protecting Boxes or Casings, of which the following is a specification.

This invention relates to electric appliance receiving and meter protecting box or casing. It is of particular utility in socalled meter installations where the electric supply wires are to be connected with certain electric connection or circuit controlling appliances and with a meter before they are carried to the translating devices served, this being merely an illustration of the several purposes accomplished by my invention int-he electric art. More specifically my invention relate's to that type of devices in which the circuit controlling instrumentali-ty is located within a box or casing and .is protectively housed therein. while the Ineteror a part thereof is she protectively encased. In. the particular embodiment of my invention herein shown and described, the meter protective functioning is obtained by the projection of a part of the meter (the terminal chamber) through a part of the casing and into the interior thereof, this portion of the casing being easily insertible and removable from the other coacting parts of the casing,

Referring to said drawings:

Figure 1 is a front view showing a casing with the lower portion broken away and a circuit controlling appurtenance mounted in said casing and also part of the terminal chamber of a meter projecting into the casremovable portion.

Fig. 4 is a transverse section on the line 4.4: of Fig. 2, looking in the direction of the arrows.

Fig. 5 is a perspective of an electric appliance receiving and meter protecting equipment with a cover.

Like characters refer to like parts throughout the several views.

Serial Filo.

Referring now particularly to the several views, 2 represents the body of a casing usually comprising a back 3, side walls 4: and ti and a bottom end wall. As shown the circuit-controlling and connecting device or appliance 6 is mounted on what l have termed the back. This, as will be clear, lS not a vital condition. That is shown as the upper end wall 7 be called 'the meter protecting end wall or a plate adapter, it being provided with a cut or opening 8 of such conformation as to straddle the terminal chamber 9 of the meter protectively combined with the casing. The manner in which this meter" is protectively arranged by the projection of the terminal chamber through a closure plate or a meter protecting wall of which that denoted by 7 is an illustration, is now well understood in the art. ln order to properly protect the meter it is important that the wall 7 be securely held in locked relation with the side walls 4 and 5, while at the same time in order to provide for the simple and expeditious placement, adjustment and manipulation oi the meter when necessary, it is desirable that this meter protecting end wall be quickly removed without the necessity of tools, such as a screw driver. The meter protecting end wall 7 in the particular form herein shown has in addition to the body, which is provided with the opening or meter straddling cut 8, the side flanges 11 and 12 and may also be provided with the base or bottom flanges l3 and 1d. The side flanges are provided preferably at a point close to the top and at the front or cover side of the casing, with the holes or openings 15, and these side flanges 11 and 12 are also provided with the grooves or channels 16 at the rear of the casing extending transvers'ely of the casing as shown. iheside walls 1' and 5 are each provided with tongues or projections as 17 which are inwardly directed and positioned, so that when the end wall '2' is in its proper place between the side walls, the tongues 17 project into or through the openings 15. lln addition to the tongues each of the side walls 4 and 5 has the inwardly directed transverse head or projection 18, and this projection or bead 18 in each case is so positioned as to enter and interlock with the groove or channel 16 in each of the side flanges of the end wall.

The side walls of the casing and the flanges 11 and 12 thus in themselves contill l i M13 30K sheet StGGl,

In order to now more clearly understand the precise cooperative functioning of e interrelated parts. will in e general describe the procedure making an installation combining my protect've casing with a. meter.
